PicoDetector

[Silver Dollar]

Here's a link to a tiny metal detector I found while researching PIC programming.

Maybe it would make a nice probe?

it is very simple
frist sure this program is ok

It seem to be based on a pulse-counting FM principle.
Fun part is that the same functionality is possible using plain old transistors. Pulse counting is a superb principle when there is ample signal to demodulate, which is the very case in demodulating a free running oscillator.

thank you Silver$... keeping in archive... in folder Pinpointers.... if you still see in net please inform and all will find a place in archive.

I built this a long time ago when I first saw it posted on a Pic site.
The code works,but the sensitivity is not good for even a pinpointer.
